LOOM HAVING RETRACTILE REEDS.

SPECIFICATION forming part of Letters Patent No. 780,737, dated January 24, 1905.

Application filed February 25, 1904; Serial No. 195,138.

To all whom it may concern.-

Be it known that I, PETER C. STADLER, a citizen of the United States, residing in Paterson, in the county of Passaiciand State of New Jersey, have invented certain new and useful Improvements in Looms Having Retractile Reeds; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to looms; and it has for its principal object to provide a loom with a reed or reeds (according to the character of the loom) adapted to retract in advance of the batten after the beating up of the weft.

Ordinarily the dents of the reed stand practically stationary against the fell of the goods through a considerable portion of each revolution of the crank shaft 6., while the cranks are moving through the forward arc of their circle of rotationwith the consequence that the dents of the reed leave a seaccessory mechanism. Fig. 3 is a top plan View of what is shown in Fig. 2. Flg. 4 showsin end elevation what is seen in Figs. 2 and 3. Fig. 5 is an enlarged detail View illustrating a part of what is shown in Figs. 2, 3, and 4, and Fig. 6 is a detail view of a certain resetting device. 4,

In said drawings, a designates the loomframe; 6, the crank-shaft; 0, the batten; d,

one of the two pitmen for transmitting motion from the crank-shaft to the batten, the same being connected at one end to a pivot on a bracket f on the batten and at its other end to a crank-pin g on a fly-wheel it on the crankshaft; 2',- the take-up mechanism; j, the warp; 7a, the woven goods; Z, 'the harness, and n the lay-swords,'the same being, as is common in German looms, hung from their upper ends in the frame a.

On the top of the batten are arranged the usual shuttle-blocks 0, in which move the shuttles p, driven in the usual manner from a rack q, set in the batten. To the under side of the batten are secured guides 1", in which move longitudinally slides s, which extend lengthwise of the warp. There may be as many of these slides and their corresponding guides as is desired or expedient, according to the number of spaces provided for in the loom. They carry at their rear ends a rod 25 and at their other ends may be provided with stop-pins u to limit their rearward movement. On the rod 6 is fulcrurned a frame consisting of a series of uprights o and pairs of strips w 01:,

the former being arranged above the latter. I

The members of both pairs of these strips are spaced by stays y, and between each pair of stays, opposite each opening between shuttleblocks, is inserted a reed a. When in position, the reed rests in a socketed block 1, while its upper end stands between the upper pair of strips w, being normally held against the front one by a plate-spring 2, secured to the rear one. This plate-spring, moreover, permits the reed to yield rearwardly in the reedframe, so that the reed will accommodate variations in thickness in the filler, and thus prevent formation of shyers (open transverse spaces) in the goods.

In brackets 3,'arranged at both the top and bottom portions of the frame, are arranged the journals 4 of squared shafts 5.

ets are preferably secured to the uprights c.

6 designates a series of vertically-movable detents arranged to slide in pairs of guides 7, one of which in each pair is secured to the batten and the other to an adjoining shuttleblock. The detent is in the form of a rod having horizontal hooks 8 projecting rear- The brack- I wardly from its ends, and the downward movement of each of said detents is limited by a stop-pin 9, adapted to take against one of the guides 7, in which position the detent is normally held by a spring 10, connecting one of said guides with a book 11 on the detent.

The squared shafts 5 carry cranks 12, which are connected by vertical connecting-rods 13, and said shafts are adapted to be oscillated by a push-rod 14, arranged to slide vertically in a guide 15, secured to one of the uprights c and pivotally connected at its upper end to a crank 16 on one of the squared shafts. Said shafts are normally held in the position shown in full lines in Fig. I by a spiral spring 17 interposed between the guide 15 and a collar 1-8 on the push-rod 14:, but are turned into the dotted-line position 19 (shown in Fig. 4) upon elevating said push-rod. In the full-line position (shown in 4) the hooks 8 take over the tops of said squared shafts and so hold the reed-frame close up to the back of the batten. When said shafts are turned into the dotted- Iine position 19, (shown in Fig. L) lugs 20, arranged on said squared shafts, engage the ends of the hooks, and so by pressing slightly upwardly-thereon cause the release of the reedframe. The reed-frame when held by the hooks compresses plate-springs 21, each secured by a screw 22, arranged at its middle portion to the back of the batten, and when the hooks are caused to release the frame the free ends of these springs, which directly impinge against the backs of the uprights 11, throw the reed-frame rearwardly, the slides s sliding in the guides 9 and the reed-frame turning on the rod tas apivot. To limit the rearward motion of the reed-frame, I provide slotted stops 23, which are pivoted in brackets 2 1, secured to the back of the shuttleblocks and receive in their slots stop-pins 25 on the sides of the uprights '0. The upper front edges of the squared shafts are rounded or beveled off, as at 26, opposite the hooks 8, so as to facilitate the hooks snapping over the tops of the squared shafts and reengaging them when the reed-frame is again forced back toward the batten.

27 is a cam secured on the crank-shaft b and having its highest point or toe 28 disposed diametrically opposite the crank-pins g. This cam is engaged by the roller 29 of a lever 30, fulcrumed in a bracket 31 and normally forced toward the cam by a spring 32. The lever is connected with a bell-crank lever 33, fulcrumed in a bracket 34:, depending from the breast-beam 35, by a coupling 36, and said bell-crank lever projects under the push-rod 1 1, which latter may carry an antifriction-roller 37, adapted to be engaged by the top of said lever 33. It is to the bell-crank lever 33 that the spring 32 aforesaid is directly connected.

38 is a rod projecting forwardly from and 5 suitably secured to the glass-bar bracket-supporting beam 39, the same having its free end tubular in form and receiving a plunger or buffer 40, which is pressed forwardly by a spiral spring 11, arranged between the head 42 of said buffer and the end of the rod 38.

13 is a pin fixed to the buffer and working in a slot &4 in the rod 38 and being adapted to limit the movement of the buffer. hen the batten recedes, the back of the reed-frame impinges against the bufi er, with the consequence that the reed-frame is pressed toward the batten until the hooks 8 wipe over the tops of the squared shafts 5 and hold the reed-frame against pressure of the springs 21.

It will be understood that there may be as many of the parts 1 1, 33, 36, 30, and 27 and their accessories as is necessary or desirable, according to the number of spaces in or width of the loom.

The operation is as follows: I'Vhile the batten is advancing the reed-frame is locked in its forward position by the detents 6. As the batten reaches its forward limit of movement z'. a, at the moment when the rods have moved the fell up to the cloth (the crankpins 9 being at this time at their foremost limit of movement)the toe 28 will have pushed the lever 30 to its rearmost limit of movement. Prior to this the push-rod 14 has advanced until its roller 37 stands over the lever 33. Therefore when the lever 30 reaches its rearmost limit the lever 33 will have been raised to its highest limit of movement, pushing up on the push-rod, and thus turning the squared shafts until they release themselves from the hooks of the detents in the manner above described. The reed-frame being thus released, it is immediately pushed bacluvard. by the springs 21. If the parts are properly adjusted, the effect of this will be that the pressure of the reeds on the fell will only last until the fell has been properly disposed with relation to the goods, whereupon it will be removed by the reeds immediately retracting. The batten now moves rearwardly and in doing so brings the reed-frame against the bu ffer aO, which latter presses the reed-frame forward until it. is again locked close to the batten by the detents 6.

It will be understood that the operation of the loom, so far as the actions of the shuttles, the harness, and other mechanism thereof are concerned, is the same as in ordinary looms.

In order to prevent the operator from getting his hand in between the batten and the reed-frame as the latter is forced up to the batten, a hand-bar 15 may be mounted above the shuttle-blocks in brackets 16, secured to said shuttle-blocks.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a loom, the combination of the frame, means for controlling the warp comprising a take-up mechanism and shed-forming mechtake-up mechanism and shed-forming mechanism, the batten structure, means for laying the filler in the shed, a reed movable in the batten structure relatively toward and away from the Woven goods, means for normally pressing said reed away from the goods,means, acting oppositely to said last-named means, for retaining said reed at its limit of movement in the batten structure where it is nearest the goods, and means for causing said reedretaining means to release the reed, substantially as described.
